The invention discloses a control method of a compressor and a refrigerant circulation system. The control method comprises the following steps of controlling the oil discharge amount of the compressor according to the duration of the low frequency operation of the compressor and / or the temperature of a motor when the compressor operates at low frequency. In the control method of the compressor, when the compressor operates at the low frequency, the oil discharge amount of the compressor is controlled according to the duration of the low frequency operation of the compressor and / or the temperature of the motor, so that refrigerant oil in the compressor can be kept at a relatively stable level, the heat dissipation of the motor in the compressor is prevented from being affected by excessivestorage of the refrigerant oil in the compressor, the stable operation of the compressor can be ensured, and the service life of the compressor can be prolonged accordingly.
Description
technical field [0001] The invention relates to the technical field of refrigerant circulation, in particular to a compressor control method and a refrigerant circulation system. Background technique [0002] The compressor is the heart of the air conditioner, and its speed directly affects the efficiency of the air conditioner. With the continuous improvement of people's living standards, the application of inverter air conditioners is becoming more and more extensive. Since the inverter air conditioner can adjust the operating speed of the compressor at any time, it can be more efficient. Reasonable use of energy, and has the advantages of low noise and fast temperature adjustment. [0003] However, the existing frequency conversion air conditioner has the problem that long-term low-frequency operation will cause the compressor to not operate normally or even shorten the service life of the compressor, and affect the cooling and heating effect.
